Once I turn onto a street where the traffic signals are coordinated, I shouldn have to stop, right?
Not necessarily. Progression of traffic on streets with coordinated traffic signals is typically designed to move traffic that came straight through the previous signalized intersection. If you turned onto the street from a side street, you may need to stop one or more times before you can get into the flow of through traffic. At some locations, it is necessary accommodate turning vehicles due to the volume of traffic. Those are evaluated on a case-by-case basis. Generally, this only occurs at major intersections.
